Abstract

L'invention concerne un procédé de formation d'un produit implantable comprenant du poly(glycérol sébacate) uréthane (PGSU) chargé avec un principe actif (API, pour "active pharmaceutical ingredient"). Le procédé comprend le fait de mélanger de façon homogène une résine de poly(glycérol sébacate) (PGS) fluide avec l'API et un catalyseur pour former un mélange de résine. Le procédé comprend également le fait de combiner de façon homogène le mélange de résine avec un isocyanate pour former un mélange réactionnel, et d'injecter le mélange réactionnel pour former le PGSU chargé avec l'API. L'invention concerne également un produit implantable comprenant un PGSU chargé avec un API. Dans certains modes de réalisation, le produit implantable comprend au moins 40 % en poids de l'API, et le produit implantable libère l'API par dégradation de la surface du PGSU à une vitesse de libération prédéfinie, pendant au moins trois mois en conditions physiologiques. Dans certains modes de réalisation, le PGSU est formé à partir d'un PGS ayant réagi avec un isocyanate dans un rapport stoechiométrique (réticulation) de l'isocyanate sur l'hydroxyle se situant dans une plage comprise entre 1 / 0,25 et 1 / 1,25.
